BACKGROUND
Natural rubber latex sensitization is caused by proteins from the latex of Hevea brasiliensis, the Brazilian rubber tree. Alternative non-cross-reactive latex rubber sources are needed for the manufacture of nonallergenic medical devices (e.g., catheters) that require elasticity, which is

BACKGROUND
Lipid transfer proteins (LTPs) are relevant allergens in certain plants. The role of the LTP of Hevea brasiliensis in the latex-fruit syndrome is widely unknown.
OBJECTIVE
To study IgE reactivity with recombinant Hevea LTP in sera of fruit-allergic adults with and without natural rubber

BACKGROUND
Component-resolved diagnosis using microarray technology has recently been introduced in clinical allergology, but its applicability in patients with natural rubber latex (NRL) allergy has not been investigated.
OBJECTIVE
To evaluate the utility of microarray-based immunoglobulin (Ig) E

BACKGROUND
Two natural rubber latex proteins, Hev b 1 and Hev b 3, have been described in spina bifida (SB)-associated latex allergy.
OBJECTIVE
The aim of this study was to clone and express Hev b 3 and to obtain the immunologic active and soluble recombinant allergen for diagnosis of SB-associated

BACKGROUND
In addition to their disease-associated handicaps, patients with spina bifida (SB) are at high risk of developing latex allergy. Individuals with SB represent a special group of latex-allergic patients, inasmuch as their IgE-binding patterns differ from those of other populations of

In this study we investigated the relationship between HLA class II alleles and the IgE-specific immune response to the 4.7 kDa polypeptide hevein of Hevea brasiliensis, a major latex allergen, 51 individuals with immediate-type latex allergy and 90 controls were examined for the polymorphisms in

Phuk-waan-ban, Euphorbiaceae Sauropus androgynus (Linn) Merr, belongs to the family Euphorbiaceae, which is the same as the rubber tree, Euphorbiaceae Hevea brasiliensis. The young leaves are edible. To the best of the authors knowledge, this is the first report of anaphylactic reaction to

Natural latex from the rubber tree Hevea brasiliensis is an allergen in persons with significant cumulative latex exposure, such as those in the health care and rubber industries, as well as those undergoing repeated surgeries, especially if they undergo surgeries early in life. Symptoms of latex

Reports of allergy to latex have been increasingly frequent during the last few years. The culprit is the natural Hevea Brasiliensis latex which is present in numerous latex-containing materials for daily use. Clinical manifestations are usually benign. Systemic manifestations have been reported

We present the cases of 5 patients with a positive clinical history of cutaneous symptoms due to contact with latex products. A latex allergological assessment was made through skin prick tests (SPTs) both with commercial latex extracts and extemporaneous glove extracts, and serum-specific IgE to

Several hybridomas were produced against antigens extracted from the latex sap of Hevea brasiliensis. One of the monoclonal antibodies (LA-E3) reacted with antigens demonstrating binding to patient sera on crossed enzyme immunoelectrophoresis. This monoclonal antibody reacted with 2 of 10 glove

For the diagnosis of IgE-mediated (immediate) hypersensitivity to natural rubber latex (NRL), skin prick testing with extracts of latex gloves has been widely used, but such extracts are difficult to standardize. The present study aimed to produce on an industrial scale an NRL extract from freshly

From a series of 30 cases of immediate allergy to the latex of Hevea Brasiliensis, the authors recall the principal clinical aspects of these allergies, specially contact urticaria (during the use of surgical or cleaning gloves) and systemic anaphylactic accidents, essentially the anaphylactic shock

In the present immunoblot study we examined IgE immune responses to natural rubber latex proteins in sera from 27 adult patients with latex allergy. We demonstrated at least 30 proteins in the rubber tree sap, of which 19 bound IgE antibodies in a heterogeneous manner in patient sera. Twenty-two of
